'HYDROCARBONBURNER SPECIFICATION frrhnng part Of Letters VNO. 241,125, dated May' 10, 1881.

Application filed March 9, 1881. (No model.)

To all whom it may concern Be it known that l, J AMES DONALD, ot'Cl'eveland, in the county of Cuyahoga and State of Ohio,have invented certain new and useful Im'- provements in Hydrocarbon-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the ari to which it` pertains to make and useit, reference being had to the accompanying drawings, which fornrparlr of this specification. l

for use in lamps, oil-stoves, or for the purpose of generating steam; and it consists in so constructing aburner that thel1ydrocarbon-oiljmayfl be consumed Without the use of a chimney and still give a clear bright flame which emits no` smoke or odor.

In the drawings, Figure 1 is a longitudinal sectional view of my burner, showin g the interior construction of the same and the manner of supplying the lame with air. Fig. 2 is a sectional view of a valve which is used in burners .of the larger size and serves to regulate the supply of air to the interiorof the flame.

A is a circular metallic cup or vessel pro` vided with a central opening, a.

Bis an inlet-pipe which enters the lower part of the cupAand serves to supply the said cup with oil. This pipe B is provided with a valve, b, for regulating the supply of oil to the cup A.

C is a circular plate, which is provided with an opening, c, in its center, which extends slightly'above the surface of said plate.

cl l are legs or supports attached to the plate C.

c c are inclines upon which the legs d d rest, and which serve to raise or lower said plate C, thus supplying more or less air to the flame through the opening between the cup A and plate G.

D is a conical-shaped flue, which is provided at its lower end with openings cl', and serves as a means for supplying the interior of the Haine with air. t i

In larger burners, such as'are used forthe purpose of generating steam,'I provide a valve, E, which regulates the quantity of air to be admitted to the interior of the tlame.

g .is a concentrator or commin gling-chamber, which is provided with an annular projection on its lower extremity. rIhis concentratpr y is placed in the central opening of the cuni-I., as shown in the drawings, but it may be cast as part oi' said cup, if desired.

F is a perforated cap, which may be placed around the opening c, and serves as a means to limit the supply of'air to the outside ofthe flame operator. e

The operation of my device isas follows: The cup or vesselAbeing filled with arefractory substance, such as ashes, asbestus, 85e., the valve in thesupply-pipe B is opened, and the oil ilows through it into the cup or vessel A and is absorbed by the substance in said cup. A lighted m atch being applied to the opening in the plate G the gases escaping from the oil are ignited, the llame spreading over the whole surface of the substance in the cup A, and the air, being drawn in through the opening between the cup A and plate G, forces. the llame through the opening in said plate C, which, in turn, causes a 'central draft through the flue D, the air being admitted to the interior ot' said flue bylmeans of openings in its lower end. This flue D is made conical in shape.- My reason for this is to cause the air to be compressed as it is drawn through said tlue until vit strikes the projection on the concentrator. It is then let free and expands in said concentrator, thus causing the air to com mingle freely with the gases and produce a perfect combustion.

The valve E, which I use in larger burners,` is lplaced below the concentrator g in such a manner that as it is raised the air is drawn throughvthe space between the outer rim ofthe valve c and its sea't under the concentrator g; hence the quantity of air to be admitted to the interior of the llame maybe regulated by raising or lowering said valve.

Any suitable means may be employed for and for the purpose shown and described.
